I m arriving in Switzerland next month, in the airport of geneva and I have to catch a train from there to go to bern. I have been told that there is a train station in the airport but I wonder if there are ticket wickets with assistants so as to buy train ticket (or cards, like the swiss pass). I ask this question because some times in the stations there aren't ticket wickets, just ticket machines and sometimes they're difficult to use if you're not familiar to them, so this makes me anxious!
Also, I suppose that there are exchange currency in the airport (again with assistants, not machines)?
And anotherquestion: how is usually the weather in Switzerlnad in October?
Thank you in advance.
